This paper provides guidelines for load rating of existing bridges. It is based on internal notes regarding criteria and practice for load rating of bridges and consideration of multiple vehicle presence over structures with varying numbers of heavy commercial vehicles. It extends the provisions of the current AS 5100 Bridge Design 2004 [1] by providing a guide for bridge designers in regards to multiple presence of heavy vehicles and loading criteria for legal, restricted and permit vehicle travel. The main objectives of this paper are to facilitate consistent rational bridge rating methods for assessment Engineers. This will foster national practices for load rating bridges and allow uniform travel potential of varying types and load configurations of vehicles.
